LeAnn is trying to stop the alleged tape from being released, but will it leak anyway?

LeAnn, 28, allegedly left the footage of her and Dean in a moving truck, and it was found by an internet forum user who claimed LeAnn was captured posing provocativly while wearing a thong, Starreports.

LeAnn’s reps say the footage doesn’t exist, while Dean told the magazine, “We were married for eight years, we did a lot of s–t. I honestly don’t even remember. I’m sure it was fun and innocent.”

We hope she’s able to block the release — how embarrassing for her and her current husband Eddie Cibrian!
